Product Description

AIR CIRCUIT BREAKER

MTW1-2000, MTW1-3200, MTW1-4000, MTW1-6300, MTW1-7500

The MTW1 series intelligent breaker is expertly crafted for the AC 50Hz distribution network, boasting a rated voltage of 400V and 690V, offering a versatile rated current range between 400A~7500A. This cutting-edge solution not only efficiently distributes electric energy but also provides unwavering protection for circuits and power equipment against potential overload, under-voltage, short circuit and single-phase earth faults. Featuring an intelligent protection feature along with precise selective protection, it remarkably enhances the reliability of the power supply and prevents

unnecessary power interruptions.The circuit breaker is distinguished by an impressive impulse withstand voltage of8000V at an altitude of 2000 meters (with adjustments for varying altitudes, ensuring a maximum not exceeding 12000V).

This exceptional product adheres to the rigorous standards of GB14048.2 for low-voltage switchgear and control equipment, specifically engineered for low-voltage circuit breakers and conforms to IEC60947-2 for low-voltage switchgear and control equipment, part two: low-voltage circuit breaker.

Product testing

Comprehensive Mechanical Operation Evaluation:

Thoroughly scrutinize the mechanical operation of the Durable 600A Drawer Air Circuit Breaker to ensure it is exceedingly flexible and steadfastly reliable.Conduct assessments on the seamless operation functionalities, such as

closing , opening , and the precise execution ofenergy storage management. Excellence in Electrical Performance Testing:Perform an insulation resistance test: Utilize a megohmmeter to meticulously measure the insulation resistance of both main and auxiliary circuits, ensuring they exceed standard requirements (customarily ≥ 1M Ω).

Power Frequency Withstand Voltage Evaluation: Administer the rated power frequency voltage (e.g., 2500V/1min) to assess the resilience and robustness of insulation performance on both main and auxiliary circuits.

Contact Resistance Examination: Precisely measure the contact resistance of the primary contact to verify it is consistently below the set threshold (typically at a micro ohm level).

Mastery in Protection Function Testing:

Assess the precision of action values and timing for protection functionalities such as

overload, short circuit

, and ground fault protection. Ensure the accurate calibrationand seamless operability

of the advanced intelligent release mechanism.
